Firewire errors with Freecom Hard Drive Quattro and linux kernel 3.13 rc8: firewire_sbp2 fw1.0: status write for unknown ORB

[<pho...@ya...>]

Hello,

I still do have the problems with my new Freecom Hard Drive on its
firewire port. Anyway, I thought I might try a new kernel to see if the
problems would go away. However the errors are still coming.

This is what I get from dmesg:

Any ideas, hints what I could try to make this work ?
